To all 'whom t may concern.' f

Be it lrnown that l, WILLIAM it. Genion, a citizen of the United States, and a resident of Jersey City, county of fiuds'on, and State of `New Jersey, have invented certain new and useful improvements in Liquidliuel itoniizers and induced-Draft Apparatus, of which the following is a specication.1

@ne important object ofthe invention is to provide a novel apparatus adapted for use in connection with furnaces of the .tire boxes of steam boilers, and designed tooperate through there box door and above the coal to produce an induced draft through the re, at the same time igniting the coal from the top, and heating the walls of the tire bon above the coal in order to `create a more rapid generation of steam than could be accomplished were the re inthe re box and the usual draft solely relied upon., in many instances, especially in the case of ships von the sea, it is necessary to get up steam in the engine boilers on'siiort notice and in the greatest haste in order to make a quick departure, and when the lires have been banked for any considerable time, as when a ship is in port, it requires a large amount of tirne and labor to break the res and produce the necessary steam pressure. To enhance the generation of steam and combustion of the coal in the re boxes in such cases where a large steam pressure is required on short notice and in the greatest baste, the present invention contemplates the use of a liquid fuel atomizer which can be inserted into a re box through the fire box door, and above the coal, the heat and flame therefrom being directed against the boiler walls, to rapidly heat the water in the boiler, the burning ofthe liquid fuel and the heat therefrom reducing an induced. draft through the coa and at the saine time igniting the coal from the top, thus eliminating the necessity of waiting for the usual draft to penetrate the re the to burn the coal in the usual manner.

Another important object of the invention is to provide a -portable liquid fuel atoroirer of the character described which can be easily and quickly transported so that the saine can be normally stored in an out-ofthe-way plaee, and carried to dre to be A door to allow the throwing in'of coal without moving the fuel tank.

With these and other objects in view which will more fully appear as the descripl tion proceeds and the nature of the4 invention is better understood, the invention consists in certain novel constructions, combination and arrangement of the parte as will be more fully'pointed out in the following description and appended claims.

For a full understanding of the invention reference is to be had `to the following description and accompanying drawings, in which:

-Figure l is a fragmentary front elevation of the re box of a conventional steam boiler, showing a liquid fuel atomizer constructed in accordance with the invention in operative position relative thereto.

f Fig. 2 is a fragmentary horizontal sectional view through the tire bon, the atomizer appearing in top plan view, and the varions adjusted positions thereof being shown in dotted and dot and dash lines.

, 3 is a side elevation of the nre bon and liquid fuel atomizer, portions of the lire bor; being' broken 'away and shown in section; and

Fig. 4; is an enlarged longitudinal sectional view through the atomizer head.

Gorresponding and lilre parts are referred to in 'the following description and indicated all the views of the drawings by the saine reference characters.

Specieally describing the present ernbodiment of the invention thev reference character t designates the re bon of a conventional steam boiler, said re bon being provided with the usual door opening o lid@ vez

which. is adapted to be normally closed by a The liquid fuel atomizer embodying the present invention when in operative position is adapted to be inserted into the door opening a and the spray therefrom directed upon the 'Walls of the iire box, or the coal in the lire box if it is desired to rapidly ignite the coal from vthe top.

The atomizer and fuel tank may be so combined as to be transported as a unit, or the atomizer may be constructed to be interchangeably connected to any one of several fuel tanks. However, both the fuel tank and atomizer are constructed to be portable so that they can be moved from one lire box to another and stored in an out-oLt-the-vvay place when not in use. The fuel tank is designated by the reference numeral l, and is provided at its top With an air pipe connection 2, which is adapted to be connected to any suitable air supply7 such as the fan blower 3. A. fuel discharge pipe lextends downwardly through the fuel tank l to a point slightly spaced from the bottom thereof and projects upwardly above the top ot the tank, the upper end thereof havingM a swivel connection member 5 adapted to receive one end of a fuel supply pipe 6, the other end of which is provided With a .second swivel connection member connected 'to one oit elbow 8j the other or which carries a third swivel connection nieniher 9 adapted to be connected to the atcniizer head llt il fuel supply regulating vi is arranged in the fuel supp mear/ei 15a through. the valve l5, the said nozzle extending into the mixing chamber l2 along the axial centerv thereof to a point slightly spaced from the fuel nozzle 14. 'lhe fuel nozzle 14 and air nozzle i8 are thus at suhstantially right angles with each other and the jets therefrom meet in a point. This causes the jets to tend to deflect each. other and the result is the thorough atolnization 0r breaking up of the liquid fuel into vapor. The arm lll of the body member ll is provided with an elongated fuel inxtire discharge nozzle 19 from 'which the fuel n1iX- ture is projected.

lin the operation of the device the fuel tank l is brought into a position adjacent the furnace or steam boiler to be operated upon and the air pipe 2 connected to the compressed air supply The fuel supply pipe 6 is connected by the swivel 5 to the fuel discharge pipe 4 in the tank and the valve .l0 opened., The compressed air acting on the surface of the fuel in the tank l forces the fuel through the pipe 6 and out of the fuel nozzle 1l in the atomizer B under pressure. he air cut-oil valve l? in the compressed air hose is opened and the air regulating valve l5' oni the atoinizer head B manipulated to the proper degree to allow the c impressed air to discharge from air nozzle The jets-ot air e .nel

pressure the a or mediate ignition of the coal is desired the spray from the liquid fuel atomizer can be caused to play directly upon the coal. The

spray can be directed upon the fire bo x walls at all points by means of the swivel connections 7 and 9, the swivel 7 allowing the atomizer head B to be swung in a vertical plane up and down, as indicated by dotted lines on Fig. 3, so as to direct the spray to either the extreme front or rear of the re box, while the swivel 9 allows the burner head B to be swung in a horizontal plane so as to direct the spray toward the sides and corners of the fire box, as indicated by dotted and dot and dash lines on Fig. 2. Further, it will be noted that the atomizer head B and fuel supply ipe 6 can be swung bodily away from the re box into an outof-the-way position by means of the swivel 5, to allow the throwing in of new coal, as indicated by dotted and dot and dash lines a: and y, respectively, on Fig. 2. The fuel tank 1 thus serves as a. support for the atomizer, and the fuel supply pipe 6 serves as a bracket arm for the atomizer, both the tank and atomizer B being portable either as a unit or separately so that the device can be utilized in connection with any of several fire boxes when it is desired to induce an unusually rapid generation of steam in the boiler and combustion of the coal in the ire box, the swivel connections allowing the atomizer to be manipulated so as to effectivel direct the flame upon all the walls of the re box and also upon the entire surface of coal from the fire box door. Further, the entire device can be quickly disassembled to occupy a minimum amount of space by detaching the atomizer head B from the fuel supply pipe 6, and detaching the pipe 6 from tank 1.

While I have shown and described only one liquid fuel atomizer and tank it will be obvious that it is within the scope of the invention to combine a plurality of atomizers with a common fuel supply pipe so comprising a liquid fuel supply fuel atomizer having a swivel connection l with the other arm of said elbow to-swing in a horizontal plane.

2. An apparatus of the class described,

tank, a vertical pipe section extending through the top of said tank and depending within the tank to a point adjacent the bottom thereof, a horizontally swinging pipe section having a swivel connection at one end with the upper end of the vertical pipe section, an elbow having a swivel connection with the free end of said horizontal pipe section, an

latomizer having a swivel connection with the free arm of said elbow and having a fuel jet communicating with the elbow and an independent air jet, a flexible air-supply hose communicating with the air jet of the atomizer, and means for supplying air under pressure to the surface of the fuel in said tank.

3. The combination with a portable liquid fuel tank, of. a pipe section communicating with the interior of said tank and connected therewith to swing relatively to the tank, an elbow pipe section having one end swiveled to the free end of said swinging pipe section, an atomizer swiveled on the other end of said elbow section and having a fuel jet communciating with said elbow and an air jet, and a iiexible air-supply conduit communicating with said air jet.
